RAILWAY-TIE.

SPECIFICATIGN forming part of Letters Patent No. 738,681, datedSeptember 8, 1903.

Application filed December 29, 1902. Serial No'. 137,054. (No model.) l

To all whom it may concern,..-

Be it known that I, ROBLEY EUGENE HEL- LER, a citizen of the UnitedStates, residing at Abingdon, in the county of Knox and State ofIllinois, have inventedl a new and useful Railway-Tie, of which thefollowing is a speci- This invention relates to metal railway-rail ties,and has for its object to produce a simply constructed and durable tiewhich will possess sufficient elasticity to yield under the weight ofthe passing trains to effect a saving in the wear of the rolling-stock,but also decrease the jar and concussion and increasing the comfort ofpassengers.

The invention consists in certain novel fea` i tures of construction, ashereinafter shown and described, and specied in the claims.

In the drawingsillustrative of the inven-4 `tion,in which correspondingparts are denoted by like designating characters in all the figures,Figure 1 is a longitudinal sectional elevation,and Fig. 2 is atransverse sectional elevation, showing one embodiment of the invention.Figs. 3 and 4 aretransverse sec- C tional views illustrating modifiedforms of thel n structure.

\ portion (indicated at 10) is somewhat thicker than the sides and ends,(indicated, respectively, at 11, 12, 13, and 14.) The base members willrest upon the ground and will conform substantially in outline to anordinary `tie and will preferably be spaced apart and embedded in theballast in the ordinary manl ner relative to the road-bed and rails.Within the base member will be inserted another box- `like intermediatemember corresponding to `the base member and resting by its bottommember 15 upon the bottom member 10 and with its side and end walls 16,17, 18,' and 19 parallel to and spaced from the side and end walls 11,12, 13, and 14, as shown, leaving a space between the side and end wallsof the two structures, as shown. A third box-like `member is providedwith a top member 2O and side and end walls 21, 22, 23, and'24,

Vadapted to it in the cavity between the base member and intermediatemember by its side and end walls, as shown, the top member thustelescoping relative to the base and intermediate member.

Within the cavity between the base and intermediate members is insertedarubber or other suitable packing or cushion 25, with which the edges ofthe side and end walls of the top.member engage when the parts areassembled, as shown. A similar yieldable cushion 26 may also be placedbetween the upper edges of the side and end walls of the intermediatemember and the upper portion of the top member, as shown.

Beneath the points wherethe rails 27 28 enl vice is the same asdisclosed by Patent No.

652,265, issued to me on the 26th day of June, 1900, and is not,therefore, further described.

Within the intermediate member between n the reinforcing portions 29 30and the bottom portion 15 of the intermediate member are arrangedsprings 35 36, the springs being heavy enough to resist the strains ofan ordinary train, but which will yield to abnormal pressure, and thusprevent Jthe breakage of the Y under pressure, and a suitable cavityfilled by a valve 37 will be provided to permit the compressingapparatus to be attached in any s uitable manner, and to prevent thisair or liquid pressure from separating the parts clampingbands 38 39 40will be secured around the assembled structure at suitable intervals tohold ICO the parts from expansion, while at the same time leaving themfree to be compressed to ka limited extent. The supporting-bands willpreferably be attached to the base .member, as by bolts 4l 42 43, asshown, and will be of sufficient strength to withstand the pressure towhich they will be subjected. By this arrangement a very compact andstrong tie is produced,- which will efficiently resist all strains towhich it will be subjected, while at the same time possessing sufficientelasticity to yield to the pressure of the passing trains `ableprotecting compoundsor ,compositionsV to prevent corrosion, and thepacking-strips -will be cemented in place to support themY and preventund ue j ar or concussion and cause the cars to run with a smoothgliding motion free from the annoying` and unpleasant jolting andswaying` so common in ruiming over the ordinary road-bed employing`rigid and lunyielding ties.

with and dependence placed upon the base member and upper member only,as shown in Fig. 3, or theupper member may be arranged with its side andend walls outside the corresponding side and end walls of the basemember, as shown in Fig. 4; but these modifications would not be adeparture from the principle of the invention, as the results producedand the manner of operation would be` the same in vall the forms shown.

When the modification shown inv Fig. 4 is used, the rubber packing 26only will be em-` ployed, and when the modification shown in Fig. 3 isemployed the packings 25 only will be used. The members of the structurewill prefi erably be of cast metal, but may be of other mate-rial, ifpreferred, as any material Which may be rendered air or liquid tight maybe employed for this purpose.

joints between the parts, the elasticity of the packing maintaining theintegrity of the joints at all times and during all the variousVrelative positions of the parts.

It is obvious that any suitable material or compound which possesses therequisite elasticity other than rubber maybe employed for 'the packingmeans, and I do not, therefore,

wish to be limited to any specific material for thispurpose.V The hollowmembers will preferably be coated or impregnated with suitwhile thefluid-filling is being inserted. Under some circumstances the side andend walls The rubber pack-1 -ings form means for effectually sealing theof the intermediate member' may be shortened or formed to extend only aportion of the distance above the portion l0 of the base member.

It will be understood that means other than the binding-bands maybeemployed for sup# porting the parts, and it will also be understood thatin assembling the parts it will be necessary to forcibly compress them,owing to the great expansive force of the springs 35 36 when placing thebands in position. The filling element may be of any suitable materialor compound or composition and may consist of air or liquid underpressure or other suitable substance or element under normal pressure.The parts may be formed of any relative size or of any suitable materialand may be modified in minor particulars without departing from theprinciple of the invention or sacrificing any of its advantages.

Having thus described the invention, what l.
